Presentation Out line

Bio processing - great potential for industriesThe bulk part of textile production migrates to the developing world, partially because of stricter environmental regulations in the industrialized countries. The developing world has the possibility to create a unique competitive advantage by promoting environmentally sustainable production process based on Biotechnology

Bamboo plant does not need any pesticides & insecticides & fungicide to grow of plant so its called as green plant.

Textiles made of bamboo fiber are eco-friendly.

Introduction

Classification of Natural Textile Fibers

Bamboo is the general name used for a number of perennial, woody-stemmed grasses

They are a popular landscape plant because they grow rapidly, are evergreens, and create a tropical or exotic atmosphere.

They are often marketed as alternative, fast-growing privacy screens. Basically bamboo is a grass; it is the worlds fastest growing Woody Plant.

Typical Layout of Wet Spinning Process WEAVING

Bamboo fibers have some properties that are not feasible i.e. it is sensitive to moisture regain and become weak as it moisture regain increase. So during the whole process the suitable rate of moisture regains is 8%-9%.

Morphological structure

Crystalline structureAccording to results of XRD, although the crystalline structure of the bamboo fiber belongs to cellulose I, it is not the same as those of flax, cotton and ramie completely.

Fine Structure

XRD Graphs of the Fibers: Bamboo Fiber, Flax, Ramie and Jute Fibers

In the angle of diffraction peaks, quite similar to that of wood, which shows overlapping of the diffraction peaks at (101) and (101) lattice plane. It may be because of a high percentage of amorphous hemi cellulose and lignin in the bamboo fiber. In addition, the degree of crystallinity of the bamboo fibers is lower than those of the flax and cotton, and similar to that of jute.The low degree of crystallinity (52.54%) for the bamboo fiber may be due to lot of substances grown with cellulose resultantly disturbing the formation of the cellulose crystalline structure during the growth of bamboo and about 20% of lignin and hemi cellulose residuals in fiber will effect testing results to some extentREFRENCE:- Dr Shah J N and Dr Shah S R.

Degree of polymerization (DP)DP of the bamboo fiber is close to that of the jute fiber, but lower than those of flax and ramie, and far lower than that of cotton. The lower DP would usually lead to lower tenacity for the fibers.The DP of cellulose in fiber also is dependent on its surroundings. Higher the lignin content is in the plant, the lower the DP of cellulose may be because of disturbance created by the non-cellulose substances during polymerization, this can be proved by the group of weak cellulose characteristic absorption peaks at the wave numbers of 10321158cm1 in the infrared spectrum of the bamboo fiber (figure-10), also, by fibre size

Limitations of Bamboo Textile

Cost is high compare to cottonFabric tend to shrink more than all cotton fabrics, therefore special laundering may be required.

The present study we carried out pretreatment, dyeing & finishing of bamboo fabric MANUFACTURED FROM natural resources.EnzymesNatural dyeNatural finishing agent

Comparison of the results between natural wet processing & conventional wet processing of bamboo fabric

Main object is to produced 100% eco-friendly bamboo fabric ---- NO hazards chemicals.

Save energy & eliminate harmful effect of effluent to preserve the green status of earth.

Scope of present study

Safer reactions

Used of renewable raw materials

Sustain biodegradability

Literature surveyed based on green status of bamboo textile.Manufacturing of bamboo fiberConventional process of bamboo textile & its involves hazardDevelopment of areas of bamboo fiber processingGreen wet processing of textiles. Bamboo processing presently is not eco-friendly We survey the eco-friendly process & also various enzymes to eliminate sodium hydroxide with enzymes. We survey the three natural dye which produced some herbal properties on bamboo textile.We survey natural finishing agent ALOE VERA which impart the special antimicrobial properties on bamboo textile.

Literature review

Out come of Literature reviewoxidative bleaching are carried out using hydrogen peroxide in conventional method.

Enzymes is a specialized protein produced within an organism which is capable of catalyzing specific chemical reaction i.e. hydrolysis, oxidation, reduction, etc.

Factors affecting enzyme activity are effect of temperature, Effect of pH, Effect of activators, Redox potential,

In the present study hemicellulase, cellulase & pectinase enzymes are used to process of eco-friendly pretreatment of bamboo fabric.

Pectinases capable of hydrolyzing pectinic substances are generally enzyme complexes containing esterases and depolymerases with random or terminal activities.
